Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed February 11, 1908. Serial No. 415,415.

To all whom it may concern: I Be it known that I, LEVI M. Nnnnn, a citizen of the United States, residing at Milford, in the county of Kosciusko and State of In-' diaiia, have invented a new and useful Improvement in Spring Binding-Posts, of which the following is a specification.

My invention relates to iln movements in connecting devices for termina wires of electric circuits.

The principal object of mv invention is to provide a simple, economical and easily-manipulated connector or spring clamp, which will beneat and compact in its structure and which may be formed in one piece stamped froura sheet of metal having the contact surfaces in holes -punched through the metal, thus iresenting the ends of the grain of the metal to the eoluluctor inserted thereinto, it being understood that the metal does not so readily corrode on the surfaces punched =aeross the grain as on the rolled surface of the sheet metal, and also that the surfaces within the holes are better protected from dirt 'and corrosion and will remain much cleaner and brighter than the exposed surface of the sheet metal, thereb msuriu a more certain and uniformly good elertrical contact. 'lllese and other objects will more war from the following specification, taken in connection with the accomninying drawings which illustrate my in volition, while the. novel features are more" particularly pointed out in the appended claims.

ln the'drawiugs Figures 1 and 2 are perspeetire views of a simple form embodying the essential features of the invention. Figs. 3 and -t,are perspectii'e views of nualilications in design. I

'lhe binding post consists of a metal punching bout u ion itself near the middle to form opposing llat surfaces 1 and 2 each of win-u. is formed tocoiiperate with the other in clamping the connecting wire; one end heiug'sonu-what narrower than the body of the connector and he-ntat right angles toward the opposing member forming a tongue 9 continuing a hole 8 punched across the.

grains of the sheet metal to provide'a eontaeting surface: the other end being foruu-d and bent. in the form of an inverted U as sbowirat It. I and 5, the renter portion 4 having a. transverse opening it for the m'lmission of the tongue 9 and'tho side. portions 3 and f5 harin r contact holes 7 hole in 5 is not risible in raw-lug, being on backside) which aline wit.h hole 8 when the opposing memhere 1 an'd2 are compressed, the slot 6 form ing; a perfect guide for the tongue 9 so that an exactalinement oi the holes 7 and 8 is assured.

In Fig. 1 the connector is shown inits simplest form and in normal condition, the ends of the opposing sides being somewhat se arated.

n Fi 2 the same connector is shown as having cen'com .iressed and connected to wire 11 which is Irmly clam wed against the metal-grain-eiul surfaces in he holes of the parts 3, 5 and 9v and securely held by the retraetive force of the opposiug'members.

In Fig. 3 the connector shown is identical with the one just describedexeept that the inverted U portion is formed. outward from the body of thel'eonnector instead of inward as in he first instance. With this construction the end portion 5 may be prolonged as shown or otherwise as adaptation to various uses may require.

In Fig. 4 the connector shown is made double, providing for two connecting wires, and isespeciallyadapted for electrically munecting and disconnecting two wires to and from each other. as is often necessary for I uniting tests of electric circuits. \Vhile this ligure illustrates a double connector italso clearly shows that a connector embodying my invention may he made wider so as to connect three or four or any desired mun- 'ber of wires'together. i

l'L-u'ing thus described my invention, what I claim and desireto secure by Letters Pat.- .rnt, is-

l. connecting device for terminal .Wires rousisllngnl a single piece of resilient sheet metal looped on it elf with the ends adapted to be normally separated from each other, said loop having one end formed into a tongue or projecting portion with a hole traversing the metal thereof, and the other end having a slot to receive the tongue and provided with holes traversing the metal thereof. the several holes alining when the tongue has, entered the slot 2. A connecting device forterminal wires consisting of a single 'piero of resilient sheet metal looped on itself with the ends adapted normally to be separatwl from each other,

one member or end having a transverse slotbetween two holes, andfbeing bent in'the nletal looped on itself with the ends adapted to be normally separated from each other,

'. sai having one end, formed. into a plurality 0 similar tongues or projectin portioos andthe other end with a plum ity of slots adapted to receive the tongues, each tongue having a hole traversing the metal thereof to'admit a connecting wire and the slotted and having means eoactin with the holes in the tongues to receive an retain the terminals of electric conductors.

4. A connecting device for terminal wires consisting of a 1e piece. of resilient sheet metal looped on i t lilf with the ends adaglted normally to be separated from each d or, one member or end has! two or'more transverse slots, each form between a set of two holes; and being bent" in such she as will allow the tongues of the posits members to enter the slots, the two he es op posite'each slot thus alinin with the hole of the engaging tongue, for t e admission of a connecting wire.

5. A connecting device for terminal wires "consisting of a single piece of resilient sheet metal, having a ho y member and an opposring member" projecting upwardly there rom, then are lel therewit then downward tower and; when compressed, through a slot in the body member, a hole being tprovided in the end portion that pa'sses into member and to admit and hold the connecting wire. v i

6. A connecting device for terminal wires consisting of a sin 1e piece of resilient sheet metal, having a be y m imber. and an tiniesing spend with a hole in thetongue of the opposing spring member, so that when the two members are sprung .will be in alinement w ereby -a connecting wire may be inserted and firmly held by the retracti've force of the opposing 1 posl atransverse slot in the middle part- Of BlIO e slot to aline with holes in the body part of such loop for the reception of the tongue of the opposin sprin member and a hole in each side 0 said 00p to corretogether the three holes spring 00 members. i

7. A connecting device for terminal wires consisting of a singlev piece of-i'esilient sheet metal,-having a body member and an 0' e spring .member pro'ecting upward'y there rom, said body Ine'm or being bent at or near its outward end first u ward, then outward, a'nd then downward, t us forming a loop similar to an inverted U, th ere loopfor the reception of the tongue-ref the cdposing s ring-member, and a hole in each s1 :hofsai loo ttlp correspond with hole.- in e to us 0 a e opposing spri membar, so iii at when the two mem bgrs' are sprung together the three holes will be ina inementwhereby a eonnectin wire may-be inserted and firmly held by e retractive force of the opposing spri members.

In testimony whereof-I ye signed my x30 name to this specificationin the'presence of two subscribing witn 1 M. NEHER.
